An attorney for National Investigators and Security declined comment about the case. The attorney for the Foxes was not in court.

The firm, hired by the parents of Riley Fox to investigate Riley’s death, claimed they were not paid for their work. In the suit, however, Riley’s parents alleged the firm misled them about its ties to the FBI.

According to the agreement to drop the lawsuit, the firm can opt to re-file its lawsuit within a year.

Kevin Fox was arrested four months after the 2004 murder of his daughter who was sexually assaulted and bound with duct tape and drowned in a Wilmington creek.

Charges were dropped eight months later after DNA evidence ruled him out as a suspect. In May 2010, convicted rapist Scott Eby confessed to Riley’s rape and murder. He was sentenced to life without parole in November 2010 after pleading guilty to the crime.
